How To Install Roman Blinds Inside Mount


Roman Blinds as a window covering

While looking for a window treatment, you, like most people will have decide whether you want blinds or curtains for your windows. This is a very important decision to make as blinds and curtains both have their unique benefits and minor complications which you would rather not put up with. This is where Roman Blinds come in.

Roman blinds are simply blinds that use fabric that is drawn up into pleats. In essence, Roman Blinds are basically a hybrid between curtains and blinds. They have the unique look and flowing fabric of curtains, but in the compact design of a regular blind. They offer privacy and have control mechanisms that offer different levels of light control. If you want to block out sunlight fully you can get blackout roman blinds. You can also get thermal blinds to regulate temperature as an energy efficient window treatment.

You also have the option of getting motorised roman blinds that can be remotely controlled. Things can be taken up a notch by getting roman blinds that can be controlled by voice command.

Inside Mount or Outside Mount?

Once you have picked your blinds you will face a very important decision, which is the method of installation. There are in essence, two ways of installing your blinds or shades, which are the inside mount method and the outside mount method. In order to figure out which works best for you and what your preference is, it is important that you note the implications of installing them in any of the two ways.

The most frequently chosen mode of installation is the inside mount. In this method of installation, the mounting brackets and end caps are installed from within the inner portion of the window frame. Most people prefer this method because they want their window treatments within the frames of the window and not out of bounds (on the walls). This makes for a visually appealing style of treating windows and saves up on some space as well. Inside mounts are possible only if windows have sufficient depth to support the blinds.

Outside mount on the other hand, is an installation method wherein the brackets are mounted on top of the window frame onto the wall (think of something like a curtain rod maybe). Whether it has a higher aesthetic appeal than the inside mount is a question of personal preference, the fact remains that the outside mount blocks more sunlight that an inside mount. This is why it is a preferred method of installation for bedrooms and dens, while inside mounts are desirable for living rooms and dining rooms as well, where a little bit of sunlight is always featured.

How to Install Roman Blinds with an Inside Mount

Follow the steps below carefully and accurately so that you can install Roman Blinds with an inside mount without seeking any professional help. These are relatively easy instructions to follow but you must always make sure you’re careful and use a diagram or video for reference –

  1. The first thing you need to do is make sure you have the right window frames and that they are capable to supporting an inside mount. This is crucial to the installing an inside mount. Make sure that your window frames go deeper than 3.5 – 4 inches (around 10.5 cm). If the frames do not go that deep, you might have to consider re-framing your windows or use an outside mount installation method.
  2. After checking the depth of the frame, you should also check if the frame is level. There is a chance that the upper portion on the inside of a window frame can be a little crooked due to ageing or foresight during construction. If the frame isn’t level, the blinds can also end up crooked after mounting. Use a level and hold it up to the upper portion of the frame and check the levelling of the frame.
  3. This step is optional and only depends on whether or not your window frames are levelled. If they are not, you can insert tiny shims to level the frame out. With the help of a hammer, pull of certain parts of the moulding around the edges of the frame. Now, place the shim on the lower end of the slanting frame and raise the frame back up. Now check the levelling once again to see if you have done it correctly.
  4. Now, turn your attention to the Roman blinds. The purpose of this step is to measure the length of the headrail of your blinds. The head rail is the hard metallic piece on top of the blind or shade. By measuring the length of the headrail, you will know the exact places where the mounting brackets must go. If the length of the headrail is more than the length of the window frame you will have to resort to an exterior mounting method.
  5. In this step, you will be marking the position of the brackets. Since you have the length of the headrails, mark the endpoints of the headrail inside your window frame. Once you have finished marking the endpoints, measure 3 inches from both sides of the frame and mark these new points with a pencil. These new points are the places in which the brackets will be mounted.
  6. Once you know the market points which signify where the brackets will go, pick up one bracket and place it over a marked point. The bracket will have one or two holes. Use a pencil to draw an ‘X’ or any other mark to differentiate from the other pencil markings. Do the same with the other bracket on the other side of the window frame. These ‘X’ marks are places where holds need to be drilled in to screw in the brackets.
  7. Use a 1/8 drill bit and make sure it touches the ‘X’ marks. Once this is done, you should drill vertically into the frame until the hole is an inch deep. You should have 2 – 4 spots to drill into. Make sure your drill pilot holes so that you don’t splinter the wood.
  8. Now place the brackets over the holes. Once the brackets are in line with the holes, insert the screws into the holes and tighten them with a screwdriver.
  9. Your Roman blinds should have brackets attached to them that will click into place when they come in contact with the brackets attached on the frame. Start sliding your shades into place until this happens.


While these steps act as a general guide, make sure to check the instructions that specifically came with your Roman blinds for more information. Installing yourself is easy and can be done with clear steps and a little bit of patience.
